STEEL SAFE COMPANY, OF NElY YORK, N. Y., A CORPORATION ACTUATING LOCKING MEANS FOR SAFES OR VAULTS.

SPECIFICATION forming part of Letters Patent No. 788,104, dated April 25, 1905. Application filed September 15, 1903. Serial No. 173,237.

To (tZ/ 117mm [19 may concern:

Be it known that I, HENRY D. HIBBARD, a citizen of the United States. residing in Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Actuating Locking Means for Safes or Vaults, of which the following is a specification.

This invention relates to the locking or bolt- [0 ing mechanism for safes or vaults, the object of the invention being to provide means for positively locking such bolting means against movement after the throwing of the bolts, thereby to prevent shifting of such bolts by concussion or vibration or in any way other than by the proper manipulation of the actuating means.

A further object of the invention is the provision of means for controlling the movement of the bolts by locking the bolt-actuating means against movement at a predetermined time.

In the drawings accompanying and forming part of this specification, Figure 1 is an interior or rear view of a single-spindle safe or vault door, showing its bolting mechanism, its actuating means, and the means for locking such actuating means against movement. Fig. 2 is a cross-sectional view taken in line 1/ (1, Fig. 1. Fig. 3 is a detail view of a part of the actuating means and the locking means. Fig. st is a detail view of a part of such actuating means, showing the clutch mechanism. Fig. 5 is a perspective view of the locking means. Fig. 6 a viewsimilar to Fig. l, illustrating an organization particularly adapted to a double-spindle safe or vault. Fig. 7 is a cross-sectional view taken on a line b b, Fig. (3. Fig. s is a detail view of a part of the actuating means, showing the locking means. Fig. 5) is a detail view of the locking means; and Figs. 10 and 11 are detail views of the locking devices, illustrating the formation of the teeth thereof.

Similar characters of reference indicate like parts throughout the several figures of the drawings.

The locking or bolting mechanism in the present organization may be similar, if desired, to that shown and described in several of the Letters Patent heretofore granted to me -for instance, Letters Patent No. 662,435, dated November .27, [900, and No. (379,378, dated July 30, 190i and therefore a general description thereof sulticient only to illustrate the present improvement is deemed necessary. The door 2 of circular formation comprises a body 3, provided with a flange &, having an offset or step 5, adapted to cooperate with a similar formation in the jamb of the body. The flange 4 is provided with a series of openings for the passage of locking-bolts 6, the inner ends or shanks of which are pivoted to a rocking plate 7 in the form of a worm-wheel 8, located on a stud 9, shown in the present instance carried by a back platelO, bolted to the flange, such bolts usually extending into softmetal inserts cast into the flange when the door and its flange are formed of one piece of unmachineable metal such, for instanee,as manganesc steel. A suitable boss 12 has heretofore been provided to engagethc inner ends or shanks of the bolts when thrown into bolting position. For operatingthese bolts to throw or retract them a suitableactuator is provided, shown in the form of a worm or worm-shaft l3, suitably mounted in bearings 14, carried by the back plate, the worm-teeth of which are in mesh with the worm of the worm-wheel 7. This worm-shaft is provided with a bevel-gear 8o 15, loosely mounted thereon, which is in mesh with a bevel-gear 1b, carried by a spindle 17, projecting through the body of the door and squared on its outer end for the reception of a crank to turn the same, and thereby the gear 15, carried by the worm-shaft. For positively connecting this loosely-mounted bevel-gear 15 with the shaft, thereby to rotate the wormshaft, suitable means is provided, shown in the present instance asa clutch or clutch mech- 9c auism one member, 18, of which is preferably formed as a part of or secured to the hub of 3 the bevel-gear 15, while the other member, 19, splined to the worm-shaft, so that when the clutch members are in engagement the bevel-gear 15 is positively connected to the worm-shaft, and this being in mesh with the gear 16 the turning of the spindle 17 will rotate the worm-shaft, and so rock the wormrocking plate and shift the bolts as required.

For shifting the splined clutch member 19 into and out of engagement with the clutch member 18 suitable means is provided, which may be substantially similar to that shown and described in my said Patent No. 679,378, it comprising a clutch-shifter 20, the bifurcated end of which is in engagement with the shiftable clutch member 19. Its opposite end is pivoted to a floating lever 21, connected with a pair of levers 22 and 23, the opposite ends of which are respectively pivoted to the bolts 24 of a pair of combination-locks 25 and 26 and which may be dogged by time-lock mechanism in the manner shown and described, if desired, in my said patent just referred to, in which a pair of dogging devices 27 and 28, controlled by the time-lock, engage, respectively, the fence of one and the bolt of the other combination-lock, although both fences or both bolts could be dogged, if preferred. When the time-lock mechanism runs down, on the operation of either combination-lock the clutch-shifter will be shifted to shift the splined clutch member 19 into engagement with the clutch member 18 and permit the operation of the worm-shaft on the rotation of the spindle 17.

From the foregoing it will be seen that when the time-lock is set and the door bolted the clutch members 18 and 19 are disengaged, so that the worm-shaft is free from connection with the combination or time lock mechanisms. The actuating mechanism, owing to its organization and being, as it is, in the form of Worm-gearing, is so powerful that the bolts are thrown outwardly with tremendous force, and consequently draw the door to its seat with corresponding pressure, so that up to the present time the possibility of opening this door by nitroglycerin or dynamite, large quantities of which have been repeatedly used, has not been found to be practicable in any possible manner. In the smaller sizes of safes, however, where it is possible to jack the safe over on its back, so as to enable the continuous use of a considerable number of sledges on the door at one time,it may be possible in time, provided sufficient force can be used, to release the strain upon the bolts, and so jar the worm-shaft to gradually rotate it to withdraw the bolts. To obviate this possible procedure, I have provided suitable means for locking or dogging the bolts, or, more particularly, locking or dogging the actuating means of such bolts. This locking means comprises in the present instance a pair of cooperating members, one member, 30, having interiorly-located projections or teeth 31, adapted to cooperate with similar projections or teeth 32, exteriorly located on the other member, 33, shown carried by or formed as a part of the shiftable clutch member 19. The member 30 is in the form of a bracket shown bolted to the back plate 10. In practice when the splined clutch member is disengaged from its companion clutch member the projections or teeth 32 thereof will be in engagement with the projections or teeth 31, carried by one of the members 30, so that the turning of the worm-shaft is not possible. This position of the partsthat is, the locking engagement of the teeth 32 with the teeth 31-is maintained so long as the time-lock is running and, in fact, until the combinationlock is properly operated, since until this step is performed it is not possible to shift the clutch-shifter, so that as the combination-lock prevents movement of this clutch-shifter it also prevents the separation of the interlocking faces 32 and 31. When, however, the clutch member 19 has been shifted to engage its companion clutch member 18, the teeth of the locking devices will be disengaged, so that on the proper turning of the spindle 17 by its crank the worm-shaft can be operated, and thereby the bolts withdrawn .or shifted.

From the foregoing it will be seen that by this simple and efficient locking means, comprising merely a pair of members and one of which may be formed as a part of or connected with the splined clutch member, while the other may be formed as a bracket provided with an annular row of interiorly-located teeth in the form of a ring, the actuating means, and thereby the bolts, are positively locked against movement, and so effective is this locking means that it was not possible to unlock the door notwithstanding many thousands of continuous blows upon the door by a considerable number of sledge-hammers,covering a period of many hours.

The teeth of the locking members have tapered or beveled ends, preferably of the character illustrated in Figs. 10 and 11, so that these tapered ends will enable the teeth of the two locking members to freely slide into engagement with each other without difficulty regardless of the position in which the wormshaft may be. By making these locking teeth or notches of the two locking members relatively small in size and of considerable number the dead-locking of the worm-shaft is readily accomplished at any point in its rotated position, thus facilitating the locking of the worm shaft, and thereby dogging the bolts, so as to fix such actuating or worm shaft positively against accidental or unintentional movement in any desired position, with a high degree of efliciency.

The mechanism shown in Figs. 6, 7, 8, and 9 is substantially similar to that shown in Figs. 1 to 7, inclusive, and 10 and 11, except that the actuating means in the former figu res is particularly adapted to a two-spindle door, and therefore embodies a pair of clutch mechanisms. The locking means in this instance is similar to that hereinbefore described, ex-

ccpt that two locking members a0 and 50 are provided. both shiftable, being pivoted in the present instance to the back plate in the organization shown. The shiftable clutch members 19 and 19' are operated in a similar manner to that hereinbefore described by a pair ofclutch-shifters 20 and 20, connected with the bolts of combination-locks. In this organization, however, it is necessary that both shiftable clutch members 19 and 19 be unlocked,or otherwise the operation of the wormshaft by either of its spindles 17 would not be possible, since so long as one of the splined clutch members is locked against movement the turning of the worm-shaft would not be possible. 'lherefore suitable means is provided to accomplish this purpose and to permit which the members and are pivotally secured, as hereinbefore described. Pivotally connected to the clutch-shifters 20 and and 20' are levers 4:1 and 42, one to each, the opposite ends of which are jointed, respectively, to the members l0 and 50, so that when the clutch-shifter of the particular combination-lock which may be operated is moved to shift its splined clutch member into engagement with the clutch member carried by the bevel-gear the leverconnected with this clutch member will swing the locking member, looking the other splined clutch member free thereof and so permit the worm-shaft to be turned. in other words, when the clutch-shifter 20 is moved to throw its splined clutch member 19 into engagement with its companion clutch member, and thereby disconnect such clutch member 15) from its locking member 50, the lever 2 will swing the locking member 40 away from the teeth of the splined clutch member 19, so that the worm-shaft may be rotated, and when the other combination-lock operated to swing the clutch-shifterQO and its splined clutch member 19into engagement with the bevel-gear clutch member the lever l1, connected with such clutch-shifter 20 will pull the pivoted locking member a0 away from the teeth of the clutch member 19, and so unlock the worm shaft and permit it to be turned. From the foregoing it will be seen that by this means the locking of the wormshaft is positivelyeffected whenever the bolts are in their protracted locking position.

Having thus described my invention, I claim l. A safe or vaultdoor bolting mechanism comprising bolts, a worm-shaft, a pair of locking members having cooperating locking faces or devices, one secured to said worm-shaft against independent rotary movement and the other supported independently of said shaft, and one movable toward and from the other and effective when in engagement therewith to prevent movement of said shaft, and means for shiftingsaid movable member.
